Several definitions that apply throughout this disclosure will now be presented.

The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The present disclosure is described in relation to a processing mechanism for machining a workpiece that can include a fixing base, a driving member, a connecting member, a cutter and a spring. The driving member can be positioned above the fixing base. One end of the connecting member can be coupled to the driving member. One end of the cutter can be fixed to an end of the connecting member away from the driving member, and the cutter can be configured to be driven to pass through the fixing base to machine the workpiece positioned under the fixing base. The spring can be positioned between the connecting member and the fixing base. The spring can be compressed when the driving member drives the cutter away from the fixing base to machine the workpiece, and the spring under compression can bias the cutter back toward the fixing base. The connecting member can include a blocking portion extending out from the end portion of the connecting member adjacent to the driving member. The spring can be sleeved on the cutter and two opposite ends of the spring can be positioned between the blocking portion and the fixing base, respectively.

The present disclosure is further described in relation to a processing device for machining a workpiece. The processing device can include a mounting member, a first processing mechanism and a second processing mechanism separately mounted on the mounting member. The second processing mechanism can include a fixing base, a driving member, a cutter and an elastic member. The fixing base and the driving member can be separately mounted on the mounting member. The driving member can be positioned above the fixing base. One end of the cutter can be fixed to the driving member, and the cutter can be driven to move passing through the fixing base and finally machine the workpiece positioned under the fixing base. The elastic member can be positioned between the driving member and the fixing base. The elastic member can be compressed during the driving member driving the cutter to move away from the fixing base to machine the workpiece, and the cutter is driven back to its original position because of an elastic force of the compressed elastic member.

FIG. 1 illustrates a processing device 100 for machining a workpiece (not shown). The processing device 100 can include a mounting member 20, a first processing mechanism 50 and a second processing mechanism 70 separately positioned on the mounting member 20. The first processing mechanism 50 can be a milling tool mechanism configured for milling the workpiece. The second processing mechanism 70 can be configured for lathing the workpiece. For simplicity, other configurations of the processing device 100, such as a fixing mechanism for coupling the mounting member 20 to the machine tool, are not described here.

The mounting member 20 can include a first end portion 22 and a second end portion 24 located oppositely to the first end portion 22. In the embodiment, the first processing mechanism 50 can be positioned on the second end portion 24.

The cutter 77 can be driven to move through the fixing base 72 and finally machine the workpiece positioned under the fixing base 72. The elastic member 79 can be positioned between the driving member 75 and the fixing base 72.

FIG. 3 illustrates in the embodiment, the fixing base 72 can be fixed on the second end portion 24 of the mounting member 20. The fixing base 72 can define a through receiving hole 725 for receiving the cutter 77.

The driving member 75 can include a driving base 752 and a driving rod 754. The driving base 752 can be fixed on the mounting member 20 and be located above the fixing base 72. The driving rod 754 can be movably coupled to an end of the driving base 752 toward the fixing base 72. In the illustrated embodiment, the driving member 75 can be a cylinder.

One end of the cutter 77 can be coupled to the driving rod 754, the other end of the cutter 77 can pass through and outstretch from the receiving hole 725 for machining the workpiece. In the illustrated embodiment, the second processing mechanism 70 can further include a connecting member 76. One end of the connecting member 76 can be coupled to an end of the driving rod 754 away from the driving member 752, the other end of the connecting member 76 can be coupled to an end of the cutter 77 adjacent to the driving member 75, thus, connecting cutter 77 with the driving rod 754.

The second processing mechanism 70 can further include two guiding sleeves 782,784, which can be configured for guiding the cutter 77 and reducing friction between the cutter 77 and the fixing base 72. The guiding sleeve 782 can be mounted and received in an end portion of the receiving hole 725 toward the driving member 75. The guiding sleeve 784 can be partially received in an end portion of the receiving hole 725 away from the driving member 75. In the illustrated embodiment, two guiding sleeves 782,784 can be linear bearing.

FIG. 1 illustrates the elastic member 79 can be sleeved on the cutter 77 and positioned between the driving member 75 and the fixing base 72, to allow the cutter 77 to move back to its original position after machining the workpiece. In the illustrated embodiment, the guiding sleeve 782 can form a flange 7822 extending out from an end portion of the guiding sleeve 782 adjacent to the driving member 75. The connecting member 76 can include a blocking portion 762 extending out from an end portion of the connecting member 76 adjacent to the driving member 75. The elastic member 79 can be a spring. Two opposite ends of the elastic member 79 can be resisted between the flange 7822 and the blocking portion 762, respectively.

In assembly, the first processing mechanism 50 and the fixing base 72 can be mounted on the mounting member 20 separately. Two guiding sleeves 782,784 can be fixed in two ends of the receiving hole 725, respectively. The driving member 75 can be mounted on the mounting member 20 and located at a side of the fixing base 72 adjacent to the first end portion 22. The connecting member 76 can be fixed to the end of the driving rod 754 adjacent to the fixing base 72. The cutter 77 can movably pass through the fixing base 72. The elastic member 79 can be sleeved on the cutter 77. Two opposite ends of the elastic member 79 can be positioned on the guiding sleeve 78 and the connecting member 76. An end of the cutter 77 away from the fixing member 72 can be coupled to the connecting member 76.

When the workpiece is milled by the first processing mechanism 50, the second processing mechanism 50 can be in an unused condition. After a milling process, the driving rod 754 moves towards the second end portion 24 to move the cutter 77 to extend from the fixing base 72 with a preset distance to lathe the workpiece positioned under the fixing base 72. The elastic member 79 remains in a compressed state during a lathing process. After the lathing process, the cutter 77 is driven back to its original position because of an elastic force of the compressed elastic member 79.

In other embodiments, the elastic member 79 is only positioned between the driving member 75 and the fixing member 72. The elastic member 79 cannot be limited to a spring. The connecting member 76 can be omitted when the cutter 77 is coupled to the driving rod 754 directly and the elastic member 79 is positioned between the fixing member 72 and the driving base 752. The guiding sleeves 782,784 can be omitted. The first processing mechanism 50 can be other processing mechanisms, such as, but not limited to a boring tool mechanism or a lathe tool mechanism. The second processing mechanism 70 can be other processing mechanisms, such as, but not limited to a milling tool mechanism.
